U.S. Government Survey Provides Snapshot of Trends in Students' Lives

Parents may no longer need to worry quite as much about their teens smoking and drinking, but texting and emailing while driving is rampant, according to a new government study of U.S. high-school students.

Some 41.4% of students said they had texted or emailed at least once while driving in the previous 30 days when asked last year, according to the broad-based study that tracks teenage behavior.
